LOCK.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed April 7,1906. Serial No. 310,528.

To all whom it may concern:

Be it known that I, CHARLES FISHER, a citizen of the United States,residing at Oak Park, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Locks, of which thefollowing is a specification, reference being had to the accompanyingdrawing, forming a part thereof.

This invention relates more particularly to key locks.

The main objects of the invention are to produce a simple and effectivelock having few parts, and generally to improve the construction andoperation of devices of this class.

It consists in certain novel features of construction and in thepeculiar arrangement and combinations of parts as hereinafterparticularly described and pointed out in the claims.

In the accompanying drawing like characters designate the same parts inthe several figures.

Figure 1 is an inverted plan view of a lock embodying the presentinvention; Fig. 2 is a cross section on the line 2, 2, Fig. 1; Fig. 3 isa top or plan view of the lock; Fig. 4 is a longitudinal section on theline 4, 4, Fig. 1, and Fig. 5 is a section on the line 5, 5, Fig. 1.

For the purpose of illustration the lock case and keeper are shown asformed integrally with a circular cover a and a cylindrical case b,portions of which appear in the drawing, but they may be made separatefrom and attached in any suitable manner to the parts which they areintended to connect, without material change in the construction andoperation of the essential parts of the lock. The lock case a is formedwith two chambers which are arranged transversely to and intersect eachother.

(I is a reciprocating bolt, preferably made of generally cylindricalform, and fitted in one of said chambers which is open at one end andclosed at the other. The bolt is formed in one side with a longitudinalgroove e and in an adjoining side with two transverse notches orrecesses f and g, each forming two opposing transverse shoulders. Ascrew h threaded in the case 0 Y and projecting into the recess fserves, by engagement with the shoulders at the ends of said recess, toretain the bolt in the case and to limit its longitudinal movementtherein. A spiral spring i inserted in the bolt chamber and bearing atone end against the closed end of said chamber, and at the other endagainst the adjacent end of the bolt tends to thrust the opposite end ofthe belt out of the case and to hold it in locked position, as shown inFig. 4.

A barrel 3' fitted to turn in the other chamber of the case is formedwith an encircling or peripheral groove or recess to fit or receive oneside of the bolt d. By

the engagement of the bolt with this recess the barrel is held axiallyfrom displacement in the case, while it is left free to turn therein.Within the peripheral recess of the barrel is formed a circular tongue70 which enters the groove 6 in the bolt and prevents the bolt fromturning in the case, while it permits free endwise movement thereof. Thebarrel is formed with a longitudinal slot 1 opening through its ends andone side thereof, and in this slot 21. key m is fitted, as shown in Fig.2. The outer end of the barrel is reduced in diameter to fit acontracted opening in the case through which it is exposed, as shown inFigs. 2, 3 and 5. The edge of the case around this opening is notched onone side to permit the insertion of the key when the slot 1 registerswith the notch, as shown in Fig. 3. The key is notched or cutaway in oneedge to clear the inwardly projecting edge of the case at the outer endof thebarrel and the adjacent side of the bolt, which serve as wards forthe lock, as shown in Fig. 2, and the bit nat its end is adapted toenter the notch or recess 9 in the bolt and by engagement witlrtheshoulders at the ends thereof to move the belt out or in. The part b towhich the lock is applied has an inturned flange 0 which in the presentinstance serves as a keeper to engage the bolt d when it is projectedfrom the case 0, but as before stated, the keeper may be made separatefrom and attached to the part to which it is applied, and may be made ofany other form suitable for the purpose.

The bolt d may be beveled at its outer end, as indicated by the dottedline on Fig. 4, so as to be sprung automatically into engagement withthe keeper 0 in bringing the parts a and I) together, but the bolt ispreferably made with two shoulders at the ends of the notch or recess 9for engagement with the key, so that .by turning the key into positionto withdraw it from the lock the bolt will be positively moved outwardinto position to receive the bit at in the notch or recess 9 when thekey is again inserted in the lock, thereby avoiding the contingency ofthe bolt sticking in the lock and the notch or recess g stopping out ofposition to receive the bit it of the key.

The parts of the lock are assembled by first inserting the barrel j inits chamber and then inserting the spring '5 and the bolt d in the otherchamber of the case 0, the bolt being held against the tension of thespring while the screw h is turned into place in the notch or recess f.The barrel j is held in place in the case by the bolt engaging theperipheral recess therein, and the bolt is prevented from turning andits notches or recesses f and g, with the shoulders at the ends thereof,are held in their proper relation to the barrel and to the key by theengagement of the tongue 70 with the lock to the various articles anduses to which it is applicable, without materially affecting itsessential features or mode of operation and Without departing from theprinciple and intended scope of the invention.

I claim:

1. In a lock the combination of a case having chambers arrangedtransversely to and intersecting each other, a reciprocating bolt fittedin one chamber and having a shoulder adapted to be engaged by a key, anda slotted key-barrel fitted in the other chamber and having a peripheralr'ecess engaging one side of tliebolt, substantially as described.

2. In a lock the combination of a case having chambers arrangedtransversely to and intersecting each other, a reciprocating bolt fittedin one chamber and formed with a longitudinal groove, and .alongitudinally slotted key-barrel fitted to turn in the other chamberand formed with a peripheral recess to receive one side of the bolt andwith a circular tongue in said recess to engagethe groove in the boltwhich has a shoulder arranged to be engaged by a key inserted in andturned with the barrel, substantially as described.

Sr In a lock the combination of a case having chambers arrangedtransversely to and intersecting each other, a reciprocating bolt fittedin one chamber, a spring interposed between one end of said chamber andthe adjacent end of the bolt and tending to thrust the opposite end ofthe belt out of the case, and a slotted key-barrel fitted to turn in theother chamber and having a peripheral recess to receive one side of thebolt, which has a shoulder arranged to be engaged by a key inserted inand turned with the barrel, substantially as described.

4. In a lock the combination of a case having chambers arrangedtransversely to and intersecting each other, a

7 bolt fitted in one of said chambers and having a recess in one sideterminating with opposing transverse shoulders, a removable stopprojecting from the case into said recess, and a longitudinally slottedkey-barrel fitted to turn in the other chamber and formed with aperipheral recess to receive one side of the boltywhich has a shoulderarranged to be engaged by the bit of a key inserted in and turned withsaid barrel, substantially as described,

In a lock the combination of a case having two chambers arrangedtransversely to and intersecting each other, a bolt fitted in one ofsaid chambers and having a recess in one side terminating with opposingtransverse shoulders, and a longitudinally slotted key-barrel fitted toturn in the other chamber andhaving a peripheral recess receiving oneside of the bolt, the shoulders on the bolt being arranged to be engagedby the bit of a key when inserted in and turned with said barrel,substantially as described.

(3. In a lock the combination of a case having chambers arrangedtransversely to and intersecting each other, a both fitted in one ofsaid chambers and having two recesses each terminating in opposingtransverse shoulders, a re movable stop projecting through the case intoone of said rec-es and a longitudinally slotted key-barrel fitted toturn in the other chamber and having a peripheral recess to receive oneside of the bolt, the other recess in the bolt being arranged to receivethe bit of a keywhen inserted in and turned with said barrel to move thebolt by engagement with the shoulders at the ends of said recess,substantially as described.

In witness whereof 1 hereto affix my signature in presence of twowitnesses.
